So with the Asian economies booming, creates non-negligible market for private aviation as more and more people are getting richer. How do you see the General Aviation market in Asia in Say, the next 5-10 years? and also, do you think there would be a growing need for Private aviation clubs?

Maybe some increase in flying in China but GA will never take-off to similar levels in Europe or North America. If anything bizjets have seen a good increase of late but negigible when it comes to light GA flying.
Japan has wealth but how many bizjets are there. Not very many.
Elsewhere in Asia, either there is no land nor air space for GA activities and the rest are developing countries with minimal GA resources.
